Abstract

Radiative cooling has witnessed substantial progress while its performance is constrained by the thermal reciprocal Kirchhoff's law. Violating Kirchhoff's law to pursue nonreciprocal radiative cooling seems promising; however, the energy conservation requirement and radiant flux integrated over the entire hemisphere make the nonreciprocal benefit insignificant. This commentary discusses the practical limits of nonreciprocal radiative cooling and points toward the future direction of directional radiative cooling.

热非互易性有助于辐射冷却吗？

辐射冷却已经取得了长足的进步，但其性能受到热倒数基尔霍夫定律的限制。违反基尔霍夫定律来追求非互反辐射冷却似乎很有希望；然而，能量守恒要求和整个半球的辐射通量积分使得非互反效益微不足道。这篇评论讨论了非互易辐射冷却的实际限制，并指出了定向辐射冷却的未来方向。
